Galaxy S2- Microphone Goes Silent During call (hardware problem) - Galaxy S II Q&A, Help & Troubleshooting

Microphone goes silent during call (hardware problem)
Hi guys, I had this problem for a long time, i want to make the story very short. My microphone becomes silent after 1 minute of use. I used the stock voice recorder to check it without the need to call someone. People get annoyed because they can't speak to me. Sometimes the microphone is silent from the very beginning of a conversation. I hear them well but they can't hear me. Once i've changed the mic flex cable/usb port plate and it looked like it worked fine for about a month. Then the problem came back. Could it be the motherboard? Did anyone experience something similar? I had to repair my camera right after buying it second hand. The technician told me the phone was in touch with water after he replaced the back camera.

bump. Just to add, weirdly my speakerphone doesn't work during calls, i don't hear people when its on, and my GPS is useless, it never finds any location. Could it be the motherboard? Pls i need your help.

[Q] No In-call audio. Suggestions?

Hello XDA!
First, some background: A few weeks ago, my phone went for a swim. I let it dry for a few days and turned it back on, but the phone wasn't very reliable (time would run slow, half the time I couldn't make calls, and the 3G wouldn't work at all). The touchscreen however was perfectly fine. So I found an eBay auction where it seemed like everything worked except the touchscreen. I bought it, and transplanted my touchscreen onto it.
Unfortunately, while most things work, I don't have any audio coming out of the front speaker, meaning I can't hear people when I call them or they call me, and if I call them, I can't hear the ringing that goes on before the person picks up. I read on some forums this was potentially a software issue, so I reflashed the latest RUU, and got nothing. I flashed KaosFroyo v24 and still have nothing.
My current work around is to wear my headphones all the time with it (which isn't TOO inconvenient, since I listen to Pandora a lot). The microphone works. The speakerphone works (since it goes through the speaker in the back).
Does anyone know if it's possible to transplant that speaker as well? It seems unlikely since I'm pretty sure it is attached to the motherboard...
Thanks!

[Q] Ear Speaker Crackle

Hello all
Got the S2 recently...was an HD2 user (with android) and am really impressed with the performance of the S2..though I am not too happy with two things.
- Battery...i just got the VillianRom installed..and I hope to see an improvement there..
- Ear speaker jarring...the ear speaker seems to crackle at certain frequencies. I checked the whole forum and there were some others with the same complaint and was asked to use the Volume+ app..which I have and to be honest i dont see much of a diffrence..the crackle is still there. I want to be sure if this is a hardware issue or a software issue...and how can I really solve it?
Can someone help?
ah.. another fellow s2 holder that has this issue.
YES! I have the same problem and its driving me crazy!!!
its random, and its buzzes, crackle or even sounds like the earspeaker is blown!
What have you done with it? I think I'll probably go change it but just checking here if you have found the solution?
there's one person with a vibrant saying he blew hot air into the earspeaker and it solved the problem (dunno if its advisable) and he didnt say how did he do that.
I seriously have no idea what you're talking about. I use Spotify non-stop on my SGS2, no crackling thing.
I'm not talking about the back speaker, its the front one where you listen to when you're in a call.
Hello! I have the same problem! Like it is distorting. I will take it to service centre today.
I really can't remember I posted that, my bad.
ok I got back my phone from Samsung Service Centre, after a second persuasion they changed the front panel (whole LCD including the front speaker, not sure if the back speaker too, I don't know the structure of the phone).
And now, it's solved!! NO MORE BUZZING when making/receiving calls!
Definitely go ask for an exchange or a change of your panel guys! It's a HARDWARE ISSUE.
Thank you for your answer! I have the same problem. They dont belive that is something wrong. They changed the speakerphone and no solution. Now they tell me that must be something wrong with our network, which I dont belive... I was also suspecting that all have the same problem, they just dont recognize.
Thanks a lot!

[Q] SGSII -Voice call problems

Another problem related to voice calls has been noticed when calling someone.
Basically it's like you have to almost eat it in order for the other person to hear you !!
Voice calls were unclear and muffled.
Returned back..
Has anyone had same issue?

No, I never had such issues.
Voice calls working fine on my phone.
The mic may be crooked inside the housing, it's surrounded by soft rubber, easily misaligned. When I first put my GS2 back together after replacing the USB flex cable I noticed a muffled sound, I opened the phone back up and made sure the mic sat proper when I put i back together the second time. This solved the problem for me.

Phone call issues, audio cuts off everytime

Im not sure if anyone else is having this issue but whenever i make a phone call the fluctuates. It like moves in waves, i hear them and then it goes quite then i hear them again. This happen on speakerphone, on regular ear piece calls and even via the audio jack. The problem also occurs when i get voice messages. It seems fine someday and then someday calls are almost impossible to hear or voice mail is impossible to hear. I have been having this issue basically since day one and im not sure what is going on. Please any help would be appreciated.
Am i the only one with this issue?

Redmi Note 3 PRO (SD) No Sound/Audio

hi..just bought this phone about 2months, now i'm facing No sound/audio at all, here's some detail and if anyone of you any good hardware repair skills here, i need your help, as i believe100% it's not the software issues:
1. phonecall, on stock MIUI (NoROOT/customkernel,pure officialrom) its freeze/hang when dialling numbers - few second latter its rebooted itself. voice recording app won't work can't use the app as its error pop-up said, and sometimes i need to hard restart to use the phone again. and its gime bootloop and drained battery (4000mah cannot even survived for 7hour), even with no internet connections the battery still drain fast.
2. when someone calling me,there's no ringtones, even when i answering the call there's no sound at all, no musics sound, any audio files i play only hisssing/noise sounds i can hear just like feedback sound.
3. Unlocking Bootloader, replacing other rom the sounds completely disapear, no hissing,noise at all (CM,Mokee) and still phone app freeze/hang when i try make a phonecall,(reboot/hardreset)the only solution to make the phone back in usable state.
4. installing Citrus ROM, the sounds back but only hissing/noise sound on sometimes i can here the sound with some feedback issues. phone app works i can make a call without freeze/hang,no reboots, but i can't totally hear someone talk to me at all, but when i turn on the loudspeaker i can hear someone talk to me (with some annoying feedback sounds),
5. as i bricked it once and need to reach testpoint so i believe its not under warranty, seal already broken.
6.ordering the parts, connector charging board(which contain whole set new audio i guess hope can fix the issues, but just noticed that if that's part causing the no sound issues, its only fix the audio such as music,ringtones..not the front speaker(phone related still not repairable)
7. trying contact some friends which some understand about hardware told me, i break down the IC Audio so its imposible to repair/change that part since its directly micro-soldered to the mainboard.
anyone have same problem as mine?, or some of you have solutions for my problem please reply .thanks

Same problem as mine.
Even the video recording do not work too.
Is there any solution how to fix it?
I use it as ipa/od without ability to make / receives any phone call, so many ppl has the same problem here seems was Xiaomi's bad hardware components, which mine believes caused by sudden-removal audio/aux jack while its still playing the musics
anyone know the average price to fix the sound ic compared to the phone? maybe 10%, 25%, 50%, or above the price of the new units?
I have the same problem,, could any one tell me where I can buy the hardware (IC sound).
Plz tell me solution. My mobile mi note 3 audio problem, audio only listen Bluetooth.

Redmi NOTE3
I need audio IC for Redmi NOTE3 we're can I buy
hello.it is an old topic. i hope it be useful for anybody else. a few days ago My redmi note 3 pro kenzo was damaged by water. after that when I turned it on, logo of my custom ROM was appear and boot loop ... First I think it was for ROM or kernel. I installed another ROM with other kernels. I could turned on my phone and enter to user interface. but everything that was related to sound ( like : camera-music-call-headphone,... ) was not work at all. I searched a lot. I found out the problem is for Audio IC (WCD9306 Audio IC) this model. https://www.deviceparts.com/wcd9306-audio-ic-for-xiaomi-redmi-note-3-ori.html
it is used in Samsung mobile phone like S4. however you can buy it. but the main problem you can't change it by your own without tools . if you are familiar with hardware it could be useful: http://www.u2ugsm.com/blog/xiaomi-redmi-note-3-ringer-solution-jumper-problem-ways/
I think cleaning IC with cleaner or alcohol might be useful. good luck
Edit: After 4 hours I turned it on and sound is back! I just cleaned it by alcohol and cleaner. but I made mistake. a little bit of that alcohol-water liquid is entered in my LCD screen. I put it in warm place and hope it will get better.
